Removing a PHP Library or Library Folder

This procedure describes how to remove a user library or library folder
from Zend Studio.
Removing a user library or library folder means that its contents will
no longer be available in Zend Studio,
including in it's functionality such as Content Assist and Refactoring.

Important Note:

If your PHP user library or library folder is associated
with specific projects, removing it will delete it from the projects as
well.

To
remove a PHP library/library folder:

Go to Window
| Preferences | PHP | PHP
Libraries.

In the PHP Libraries Preferences page select
the user library or library folder to remove and click Remove. (Removing a user
library will remove all of the folders within it as well.) Your user library or library folder is deleted.
